MOS A9 Kraft Envelopes 5.75 x 8.75 in 500 Pack - Heavyweight Self-Seal

In this review the MOS A9 Kraft Envelopes are evaluated for card makers, event planners, and small businesses that need a large supply of reliably sized envelopes. The bottom line: these envelopes shine for anyone sending 5 x 8 in invitations or 4 x 8 in notecards because of their consistent sizing and the convenience of a peel-and-seal adhesive. The pack of 500 provides clear value, and the kraft finish gives a simple, rustic look suitable for wedding invitations, RSVPs, greeting cards, and everyday business mailings.

Key Features

• Perfect A9 size: Sized to 5.75 x 8.75 in to fit 5 x 8 in cards and 4 x 8 in notecards without excess movement in transit.
• Self-seal adhesive: Peel-and-seal closure makes assembly fast and secure, eliminating the need for licking or extra tape.
• Printer compatible: Works with both inkjet and laser printers so you can add printed addresses or designs at home or in the office.
• Kraft finish: Brown kraft provides a natural, versatile look suitable for weddings, parties and business mailings.
• Bulk pack: A 500 pack supplies large projects and recurring mailings while keeping per-envelope cost low.

Who It's For

These envelopes are ideal for crafters, event coordinators, and small businesses that send invitations, RSVP cards, or greeting cards in bulk and want a consistent, printer-friendly envelope with a rustic kraft appearance. The 500 count and peel-and-seal feature save time when preparing large mailings and make them practical for wedding suites and party invitations.

Those who need premium heavy-cardstock mailers for fragile items, unusually long flaps, or a variety of colors may want to look elsewhere; the MOS A9 focuses on standard kraft and white options and a straightforward, economical construction rather than specialty finishes or extra-thick liners.
